Energyflo’s Dynamic Breathing Building concept is being installed in Lomond Timber Frame’s open panel timber frame system, with conventional insulation materials eschewed in favour of Energyflo cells fitting between the studs.

The cells pre-heats air entering the building during winter and cools it in the summer, while reducing building fabric heat loss.

“Developing the technology for use in open panel timber frames is a great step forward,” said Dr Andrew Peacock, Energyflo’s product development director.

“We believe this system could mean significant reductions in energy consumption compared with conventional thermal insulation.”

It has been piloted in a roof application as part of a mechanical ventilation heat recovery system at a housing development in Edinburgh by CALA, supported by the Carbon Trust. BBA certification has also been achieved, covering installation in walls, roofs and floors in residential and non-residential buildings.

The pilot “Hazeldean” house was completed in May 2007, and its performance monitored ever since.

Energyflo Construction Technologies claims the results show a 66% performance increase compared with UK average dwellings and 35% better than Building Regulations.
